Abstract: A camera attachment for measuring a temperature of a surface, and related methods of measuring the temperature of the surface, employ a temperature reactive material that is thermally coupled with the surface and imaged to provide image data of the temperature reactive material that is analyzed to measure the temperature. A camera attachment for measuring a temperature of a surface includes a distal surface configured to be thermally coupled with the surface, a frame configured to be coupled with a camera that has a field of view, and a temperature reactive material coupled with the frame and thermally coupled with the distal surface. The frame positions the temperature reactive material within the field of view of the camera so that an image captured by the camera includes at least a portion of the temperature reactive material.

Abstract: A sleep monitor includes a layered sensor that includes at least one substrate layer that includes multiple laterally adjacent substrates. The substrate layer may be formed by interdigitating fingers of a first sheet with fingers of a second sheet. Combining multiple substrates in a single layer of a layered sensor may allow multiple materials and/or sensing mechanisms to be combined together in a single layer.

Abstract: A pulse transit time is measured non-invasively and used to calculate a blood pressure value. A method of determining one or more blood pressure values includes propagating an alternating drive current through a thorax of a subject via electrodes located on a wrist-worn device. Resulting voltage levels of the subject are sensed by the wrist-worn device. The voltage levels are processed to detect when a volume of blood is ejected from the left ventricle. Output from a pulse arrival sensor coupled to the wrist-worn device is processed to detect when a blood pressure pulse generated by ejection of the volume of blood from the left ventricle arrives at the wrist. A pulse transit time (PTT) for transit of the blood pressure pulse from the left ventricle to the wrist is calculated. One or more blood pressure values for the subject are determined based on the PTT.

Abstract: A blood pressure cuff includes a support band that is selectively reconfigured between a flexible standby configuration and a measurement configuration. A blood pressure cuff includes an inflatable bladder, a support band, and a control unit. The support band is attached to and surrounds the inflatable bladder. The support band is reconfigurable, in response to an input from the control unit, from a standby configuration for between blood pressure measurements to a measurement configuration for constraining the inflatable bladder while the inflatable bladder is in an inflated state during a blood pressure measurement. The control unit includes a bladder pump for inflation of the inflatable bladder during a blood pressure measurement and controls the selective reconfiguration of the support band.

Abstract: Embodiments include a blood pressure measurement device that includes a cuff for measuring blood pressure of a user. The cuff may include a bladder assembly configured to retain a fluid within an internal chamber where the bladder assembly is formed from a first cell defining a first portion of the internal chamber that is connected with a second cell defining a second portion of the internal chamber. The bladder assembly can also include a fluid passage that is in fluid communication with the first cell and the second cell and coupled with a reservoir. The bladder assembly can exchange the fluid with the reservoir and be configured to increase in length when a volume of the fluid in the internal chamber decreases, and decrease in length when the volume of the fluid in the internal chamber increases.

Abstract: The present invention generally relates to the measuring and monitoring of blood pressure. More specifically, embodiments may apply the theory of applanation tonometry for the measurement of blood pressure. Some embodiments provide a method for measuring mean arterial pressure. Some embodiments provide a device that may be worn by a user that may non-invasively measure and monitor blood pressure of a user. In some embodiments, the invention generally relates to sensor arrays for use with a wrist-worn device to measure blood pressure. Embodiments of the sensor array designs described may be configured to improve resolution by decoupling nodes of the sensor array.

Abstract: Wrist-worn devices and related methods measure a pulse transit time non-invasively and calculate a blood pressure value using the pulse transit time. A wrist-worn device include a wrist-worn elongate band, at least four EKG or ICG electrodes coupled to the wrist-worn device for detecting a ventricular ejection of a heart, a photo-plethysmogram (PPG) sensor coupled to the wrist-worn device for detecting arrival of a blood pressure pulse at the user's wrist, and a controller configured to calculate a pulse transit time (PTT) for the blood pressure pulse. The controller calculates one or more blood pressure values for the user based on the PTT.

Abstract: An interface pressure sensor includes a fluid pressure sensor disposed in a volume defined by a shear wall. The volume is enclosed, and the fluid pressure sensor is encapsulated by, an infill material. The infill material defines a sensing surface that, when pressed, can impart a force that is detectable by the fluid pressure sensor.

Abstract: Embodiments are directed to systems and techniques for tracking menstrual cycles, which can include receiving temperature measurements from an array of temperature sensors positioned on a bed. A use period for the array can be determined when temperature measurements from at least one temperature sensor of the one or more temperature sensors exceed a first temperature threshold. In some embodiments, for each use period in a set of two or more use periods, a temperature of the user using the set of temperatures from the respective use period can be determined. After determining the temperature of the user for each use period in the set of two or more use periods, at least one change in the temperature of the user between different use periods can be identified. An ovulation day of the user based on the at least one change in the temperature of the user can be estimated.

Abstract: Embodiments are directed to a blood pressure measurement device that includes a cuff configured to wrap around a limb of a user when the cuff is worn by the user, a bladder coupled to the cuff and configured to compress the limb when inflated, and a pump operative to inflate the bladder. The blood pressure measurement device can also include a valve positioned between the bladder and the pump and configured to operate in a first state that allows air from the pump to enter the bladder and prevent air from leaving the bladder. The valve can also be configured to operate in a second state that allows air to leave the bladder. The blood pressure measurement device can also include a vent positioned between the bladder and an external environment and configured to continuously release air from the bladder.
